I'm trying to follow the gnomon ground blast tutorial however there's a section towards the end where a conditional mel script is trying to control particle emission based on two factors, I think speed and height of the emitter.
Basically the tutorial states 'if' the emitter is traveling at this speed 'and' is this height then stop particle emission. The problem I'm having is the tutor types some form of shorthand for the 'and' command and it appears to small on screen to read. It looks something like &&but is not this as I've tried it! I've attached a screen capture of the mystery command below.
